The answer is b hope it helps
We can use ratios to find the answer to this.
Set up the ratio.
3/4 / 18/7 = x / 1
Multiply both sides by 1
3/4 / 18/7 = x
Inverse 18/7 to 7/18 so we can multiply.
3/4 * 7/18 = x
Multiply.
21/72 = x
Simplify7/24 = x
Therefore, 7/24 cups of oats is used per pound.
Given mean =122.3 and standard deviation =18.5
≈2.49
As a general rule z-scores lower than -1.96 or higher than 1.96 are considered unusual.
Since our z-score = 2.49>1.96 , it is unusual.
Hence correct option is 'C' = "2.49 ; unusual"
